X11 with KDE from fink

I finally have Apple's X11

working with KDE from Fink
!
I install KDE from fink as usual: "sudo apt-get install kdebase3". After
a dozen minutes of download, install and setup, and follow the instruction
listed in "apt-cache show kdebase3", I clicked the X11 icon from Dock to
launch. KDE was loaded properly and everything seems functional as well.
Interestingly, KDE windows have the
Aqua look-and-feel. It may be because it runs on top of aqua Window Manager.
But there are something need to polish:

• The fonts look not very great. I previously have XDarwin + XFree86 from fink
  and it looks better.
• Bugs in icon zooming on the panel. The zoomed icons seem being placed
  behind the panel.

Now, I have Safari running together with KDE on the same display. It is a advantage
but also a disadvantage. Since X11 does not support rootless, they are all displayed
in the same space. I cannot switch between MacOS X Aqua and X Window like
I used XDarwin before.
